## Which one, for what

### Azure Translator (BB)

Good for: Azure shops that want cheap NMT at volume, Entra ID auth and a choice of an LLM per request for tone and gender.

Ahead on:
- Reliability, 83 against 55
- Agent ergonomics, 82 against 70
- Security & auth, 75 against 58

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: The 2026-06-06 schema breaks v3.0 clients and drops BreakSentence and dictionary lookups from the spec

### Phrase (B)

Good for: Teams that keep translation projects, term bases and translation memories in Phrase and want an agent to run them, or to translate through engines chosen per language pair.

Ahead on:
- Payments & pricing, 30 against 20
- Maintenance & community, 83 against 70

Also in its favour:
- Free to start without a card

Watch for: status.phrase.com lists 14 incidents between 10 July and 8 October 2026, two marked critical and ten major, most confined to one component

## Verdicts

**Azure Translator.** $10 per million characters pay as you go, 2 million free a month on F0, commitment overage down to $5.50. The 2026-06-06 schema breaks v3.0 clients and drops BreakSentence and dictionary lookups from the spec.

**Phrase.** Nine APIs with public OpenAPI specs, Markdown docs and a hosted MCP server that signs in with OAuth and separates view, create and delete consents. The status page lists 14 incidents in 90 days, 12 marked major or critical. Capacity top-up prices aren't public, and the terms permit training some models on customer content and prohibit benchmarking.

## Before you call either

### Azure Translator

1. Send `Ocp-Apim-Subscription-Region` with the key for a regional resource
2. Pin `api-version=3.0` until your client handles the 2026-06-06 `inputs` and `value` shape
3. Batch up to 1,000 strings a call rather than one call per string
4. Spread load across the hour, since the character caps are hourly and bursts get 429
5. Treat 403001 as the free quota running out, not a permissions error

### Phrase

1. Exchange a Phrase Platform API token at `https://eu.phrase.com/idm/oauth/token` (or `us.phrase.com`) for a Bearer JWT, which lasts about four hours, and refresh it before it expires
2. Send a `User-Agent` header naming your application on every Strings and TMS call. The Strings API answers 400 without one
3. Keep Strings calls under 1,000 in five minutes and four in parallel, and read `X-Rate-Limit-Reset` and `X-Rate-Limit-Reason` on a 429
4. Send at most six texts of 2,000 characters to `/v2/textTranslations`, with `consumerId` and `targetLang`. Term bases and translation memories work only with an AI translation agent profile
5. Use the MCP URL for the account's region, `https://mcp.eu.phrase.com` or `https://mcp.us.phrase.com`, and ask the user for the view consent alone unless the task writes
